Bruce L. Davis is CEO & Chairman at Digimarc CORP (DMRC). They have made 65 open-market trades across 1 company since 2011, most recently 2021-04-12.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
0 open-market purchases, against 65 sales. Too few scored purchases to measure a record yet.
